I had a Takeda SRI laying around from my old 2011 Accord V6. Since there are no kits for the 4th gen Odyssey, I figured I'd see if it fits. Turns out it fits without much modification. The air sensor fit in perfectly to the tube. Here is a picture of it installed.
It would be better if I could get it to the other side of the battery, but it wasn't long enough and it put the sensor in a bad spot too.
Performance and fuel economy are (as always) negligible if any, but it certainly sounds better under load. The nice thing is, like my old Accord, when you are just cruising or under light throttle, its barely noticeable. I have some video that I'm going to edit and throw onto youtube at a later date. I will update with the video once I have a chance to edit it.
